A Preppy Summer Wedding in Washington, D.C.

Steps from the White House, one couple hosts a romantic, sophisticated fete with pink accents on everything from the cocktail bar to the bouquets—and the most adorable flower girl this side of the Potomac River.

A hard hat might not be every girl's best look—but the bright yellow helmet certainly worked for Elizabeth when she met Louis for the first time in a construction zone. "Louis was working as a contractor for a sustainable school project I was managing," explains Elizabeth, a financial manager at the World Wildlife Fund, Inc. "Even though we were both wearing hard hats, there was an instant connection at the coordination meeting."

For their June nuptials, the couple enlisted the help of Ritzy Bee Events to orchestrate a pale pink and green event that was at once "soft, romantic and simply sophisticated," the bride says. "Ritzy Bee Events took our scattered, disconnected thoughts and preferences and turned them into an absolutely perfect wedding."

The bride's simple sheath was made by Amsale. The A-line gown included the "perfect pop of interest," as Elizabeth says: A vertical bow down its back. She carried a winter white bouquet of roses and hydrangeas tied with pink satin ribbon.

Bridesmaids wore duponi dresses by Lula Kate, which each attendant chose herself. "I liked the look of short dresses for a summer wedding," the bride explains. "They are a little less formal, which worked for our overall look."

The couple's 3-year-old niece and goddaughter, Lily Kate, served as their flower girl. The child also played a special role in Louis' proposal; it was Lily Kate who delivered Elizabeth's engagement ring. On a walk through a park, Elizabeth recalls, "I turned around to see 2-year-old Lily Kate streaking toward us wielding a juice box in one hand and a very recognizable red box in the other. She came straight over, handed me the box and showed me her shirt, which read, 'Will you marry my Nouno,'" the Greek word for godfather.

During the couple's traditional Greek Orthodox ceremony at Saint Sophia Greek Orthodox Cathedral, Elizabeth and Louis didn't exchange vows. "In fact, the bride and groom don't speak at all," Elizabeth explains. Instead, the service includes a crowning, in which connected ribbon wreaths are placed atop the bride and groom's heads to symbolize their union. "To help our non-Greek guests understand, we turned our wedding program into a 12-page guide to the service," the bride says.

Decatur House on Lafayette Square, where Elizabeth and Louis held their evening wedding reception, was "a joyously lucky find," the bride says. The couple fell for its garden terrace and location minutes from the White House, describing it as the "best of all possible worlds."

Elizabeth says "an absolutely adorable watermelon and blue cheese salad that included a heart-shaped sesame seed cracker" was the highlight of the couple's wedding menu. "The guests loved it—perfect for a wedding and so delicious!"

But the couple's cake was hardly their only sweet after-dinner snack. Elizabeth and Louis also offered guests an ice cream bar, where they could scoop up their favorite flavor and top it with an assortment of nuts and sprinkles.

Elizabeth and Louis didn't want a big band crowding their limited outdoor tent space, so they hired five musicians to keep guests on the dance floor all night long. "They learned our first dance song, Grow Old With Me by the Postal Service, and they nailed it," Elizabeth says.

The couple credits Ritzy Bee Events for pulling off their flawless fete. "Ritzy Bee Events took our ideas and weaved their magic and perfected every tiny detail of the day," Elizabeth says. "I am sure it sounds cliche, but I just can't imagine a more perfect, amazing, beautiful and blissfully happy day. Louis and I were smiling from ear to ear non-stop from the moment we woke up until we fell asleep."
